Hi all,

Something I really miss from other DAWs is smart disable of effects to save on CPU. On my laptop i can run out of real-time CPU quickly.

This feature would include:

Audio detection-based disabling of plugins in the style of FL Studio - when the channel is silent or drops below a certain level, the DAW automatically disables the effects freeing up CPU. A selectable threshold would be nice too.

An per-channel (or global) option to automatically disable all plug-ins on the mute of a channel, as happens in REAPER. This can cause a delay when un-muting, but having the option would be great for high-cpu effect racks.

This whole feature would be very useful for people working on non-optimal systems, which is probably most users.

At the moment, one can be running with muted or silent channels hogging vast amounts of CPU

The easiest way to go about it is put the effects you really need as Event Fx and render. Saves up a lot of CPU. I use a Intel Celeron Processor 2.41 GHz and 2GB HDD and using that process i can make monster scores with up to 110 to 120 tracks. i hope it helps.

From my experience with Reaper doing this, I could often drop my CPU usage by 90% just by clicking that option in the settings. That takes about 3 seconds to do. Rendering all the Events with FX would do the same thing, but take a lot longer to do. I just tried it in my current project where only 8 events had fx, and it said it would take 36 minutes to render. So, no. Not an equivalent workaround.
